Hawthorne Effect

By , black-rose-bielefeld.de Guide


A term referring to the tendency of some people to work harder and perform better when they are participants in an experiment. Individuals may change their behavior due to the attention they are receiving from researchers rather than because of any manipulation of independent variables.

This effect was first discovered and named by researchers at Harvard University who were studying the relationship between productivity and work environment. Researchers conducted these experiments at the Hawthorne Works plant of Western Electric. The study was originally commissioned to determine if increasing or decreasing the amount of light workers received increased or decreased worker productivity. The researchers found that productivity increased due to attention from the research team and not because of changes to the experimental variable.

Later research into the Hawthorne effect has suggested that the original results may have been overstated. In 2009, researchers at the University of Chicago reanalyzed the original data and found that other factors also played a role in productivity and that the effect originally described was weak at best.
